Draw a triangle for each problem with the correct properties. Solve the triangle for each problem.

A pine tree growing on a hillside makes a 750 angle with the hill. From a point 80 feet up the hill, the angle of elevation to the top of the tree is 620 and the angle of depression to the bottom is 23. Find, to the nearest tenth of a foot, the height of the tree. 4. A pier forms an 850 angle with a straight shore. At a distance of 100 feet from the pier, the line of sight to the tip forms a 37 angle. Find the length of the pier to the nearest tenth of a foot. 5. When the angle of elevation of the sun is 62", a telephone pole that is tilted at an angle of S' directly away from the sun casts a shadow 20 feet long. Determine the length of the pole to the nearest tenth of a foot
